Answer:
280 miles
Step-by-step explanation:
It is given that :
Scale : 1.25 inches = 50 miles
In the map the distance between Piedmont and Tulsa is = 3.5 inches
So the actual distance between Piedmont and Tulsa in miles is given by :
1.25 inches = 50 miles
So, 3.5 inches = [tex]$\frac{50 \times 3.5}{1.25}$[/tex] miles
= 140 miles.
So when we go from Piedmont to Tulsa, it is 140 miles and we go back from Tulsa to Piedmont, it is another 140 miles.
Therefore, total distance = 140 + 140
= 280 miles

Answer:
x = 5.
y = -2
Step-by-step explanation:
y = x - 7
2x + y = 8
substitute the first equation into the second
2x + (x -7) = 8
2x + x - 7 = 8
3x - 7 = 8
3x = 8 + 7
3x/3 = 15/3
x = 5.
substitute 5 in the second equation
y = 5 - 7
y = -2
two angles of a quadrilateral are 67 and 100. what is the sum of the other two angles
Answer:
93
Step-by-step explanation:
what is the perimeter of figure B ?
Answer:
35 for perimeter of b
122.5 for perimeter of a
Step-by-step explanation:
To find the perimeter, you add all of the values of the outside of the shape together. Since 12+9+9+5 = 35, the answer is 35.
Okay, so what you have to do is set up a proportion for a to b. To do that, you have to have a fraction where a is the numerator and b is the denominator. 7/2 equals x/35. Then cross multiply
7*35 = 2x
x = 122.5 :)
Answer:
The perimeter is 35.
Step-by-step explanation:
To find perimeter, add all the sides together.
9 + 9 + 5 + 12 = 35
The perimeter is 35.
George and carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 350 miles in total, and they biked 80 kilometers more than they were bused.
Complete question − How many kilometres did they travel by bus and by bicycle.
Answer:George and carmen traveled by bus in 135km and by bikein 215km
Step-by-step explanation:
Total Miles traveled = 350 miles
Let Number of kilometres they traveled with bus = x
and Let Number of kilometres they traveled with bike = x + 80
so that the total distance traveled with bus and bike be expressed as
x + x + 80 = 350 miles
2x + 80 = 350 miles
2x = 350 − 80
2x =270
x=135
George and Carmen traveled by bus in 135km
and by bicycle=x + 80 = 135 km + 80 =215km
Franklin needs 1.25 meters of ribbon to wrap each gift. He has a spool of ribbon that contains 25 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of the same dimension can he wrap using the spool of ribbon?
Answer:
6
Step-by-step explanation:
convert 1.25 meters to feet
1 meter = 3 feet
1.25 meters = 1.25 x 3 = 3.75 feet
Number of gifts he can warp = 25 feet / 3.75 = 6.6

Answer:
m<BDC = 60 degrees
Step-by-step explanation:
m<EBD is 120, m<EBC = 180 (it's a straight angle) so m<DBC = 180-120= 60 degrees.
All angles in a triangle add up to 180. 60+60+x=180. 180-120=x=60.

Calculate the geometric mean of 12 and 20
Answer:
The Geometric mean of two numbers is the square root of their product.
Given numbers are 12,20.
Geometric mean = √(12*20)
= √240.
= 15.49.
= 15.5.
The geometric mean of 12 and 20 is 4√15.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 3 + 3x + 4y = 7 is an expression.
We have,
The geometric mean of a and b is √(ab).
Now,
a = 12 and b = 20
so,
The geometric mean of 12 and 20.
= √(12 x 20)
= √240
= 4√15
Thus,
The geometric mean of 12 and 20 is 4√15.

The straight line y = 3x +2 intersects the curve y = 2x^2 + 7x-11 at two points. Find the coordinates of these two points Give your answers correct to 2 decimal places.
Given:
The equation are
[tex]y=3x+2[/tex]
[tex]y=2x^2+7x-11[/tex]
To find:
The coordinates of intersection points.
Solution:
We have,
[tex]y=3x+2[/tex] ...(i)
[tex]y=2x^2+7x-11[/tex] ...(ii)
From (i) and (ii), we get
[tex]3x+2=2x^2+7x-11[/tex]
[tex]0=2x^2+7x-11-3x-2[/tex]
[tex]0=2x^2+4x-13[/tex]
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then by quadratic formula:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
In the equation [tex]0=2x^2+4x-13[/tex], we have [tex]a=2,b=4,c=-13[/tex].
Using quadratic formula, we get
[tex]x=\dfrac{-4\pm \sqrt{4^2-4(2)(-13)}}{2(2)}[/tex]
[tex]x=\dfrac{-4\pm \sqrt{16+104}}{4}[/tex]
[tex]x=\dfrac{-4\pm \sqrt{120}}{4}[/tex]
Now,
[tex]x=\dfrac{-4+\sqrt{120}}{4}[/tex] and [tex]x=\dfrac{-4-\sqrt{120}}{4}[/tex]
[tex]x=1.7386[/tex] and [tex]x=-3.7386[/tex]
[tex]x\approx 1.74[/tex] and [tex]x\approx -3.74[/tex]
Putting x=1.74 in (i), we get
[tex]y=3(1.74)+2[/tex]
[tex]y=5.22+2[/tex]
[tex]y=7.22[/tex]
Putting x=-3.74 in (i), we get
[tex]y=3(-3.74)+2[/tex]
[tex]y=-11.22+2[/tex]
[tex]y=-9.22[/tex]
Therefore, the coordinates of the intersection points are (1.74, 7.22) and (-3.74,-9.22).

Please help me find the value of x in the rectangle ABCD
Answer:
x = 52
Step-by-step explanation:
Hello there!
All of the angles in a rectangle are right angles
if a right angle has a measure of 90 degrees then we can find x by subtracting the given angle from 90
90 - 38 = 52 so we can conclude that x= 52
Step-by-step explanation:
Each angle in a quadrilateral is 90⁰ therefore 38⁰+x=90⁰
hence x=90⁰-38⁰ which gives you 52⁰

The composition g(f(x)) is:

Step-by-step explanation:
b) g(f(x)) is a function composition.
So we will have:
[tex]g(f(x))=(f(x))^{2}+1[/tex]
[tex]g(f(x))=(2x-3)^{2}+1[/tex]
[tex]g(f(x))=4x^{2}-12x+9+1[/tex]
[tex]g(f(x))=4x^{2}-12x+10[/tex]
Here:
a is 4
b is -12
c is 10
